"Did They Really Do it - From Lizzie Borden to the 20th Hijacker" by Fred Rosen, 2006, for $15.99. I'm not familiar with this one. Has anyone read it?
A copy of "Did Lizzie Borden Axe for it" is for sale at Limelight Bookshop for $49.85.
And saving the best for last, "Miss Lizzie" by Satterthwait is selling for $400 from 'Ken Lopez, Bookseller, ABAA, Hadley, MA'. It's listed as 'scarce' (I think a lot of people threw theirs out), 1st edition (would that ever go into a second printing??), and it has some "publisher's promotional" things in it.
I think this is the worst Lizzie book ever written.
